The captivating story behind one of humanity’s greatest achievements in exploration: NASA’s Voyager mission, the twin spacecrafts which revolutionized our understanding of our own solar system.

Launched forty years ago, the spacecrafts - each with less computing power than a cell phone—used slingshot trajectories to visit Jupiter, Saturn, Uranus and Neptune. They sent back unprecedented images and data from the spectacular outer planets and their many peculiar moons. They also each carry with them the iconic golden record with greetings, music and images from Earth—a gift for any aliens that might one day find it. A billion years from now, the Voyagers and their golden records will still be sailing on—perhaps the only remaining evidence that humanity ever existed.

The Farthest celebrates these magnificent machines, the men and women who built them and the vision that propelled them farther than anyone could ever have hoped.
